Description
A mechanism for locally density-dependent dynamic parton rearrangement and
fusion has been implemented into the Ultra-relativistic Quantum Molecular
Dynamics (UrQMD) approach. The same mechanism has been previously built in
the Quark Gluon String Model (QGSM). This rearrangement and fusion approach
based on parton coalescence ideas enables the description of multi-particle
interactions, namely 3 -> 3 and 3 -> 2, between (pre-)hadronic states in
addition to standard binary interactions. The UrQMD model (v2.3) extended
by these additional processes allows to investigate implications of
multi-particle interactions on the reaction dynamics of ultra-relativistic
heavy-ion collisions. The mechanism, its implementation and first results
of this investigation, e.g. implications on the kinetic equilibration and
on measurable observables like spectra of final hadrons, will be presented
and discussed.
